I never could find a baseplate that had magnets on the bottom side, so I created a remix of one of my favorite baseplates by RIP_Plu_Koon, but made some modifications to reduce plastic, print times, magnet usage, and assembly time. Here are some videos I did on the design.

• Magnet Baseplate Part 1: The Idea

• Magnet Baseplate Part 2: Show & Tell

• Magnet Baseplate Part 3: These magnets are STRONG

Most of my storage racks and drawers are metal, and securing via magnets is the way to go. Their baseplates are my all time favorites and I use them everywhere, but I wanted to make some changes. 

• Support for magnets, but only facing the bottom. (I don't need magnet bins)

• Compatible with much larger magnets

• Only spots for magnets in the corners and center to reduce plastic waste, print times, number of magnets needed. 

For right now, I only had time to draft up the 5x5 version, so that is all that is available. But, I'm sharing the .STEP file in case anyone else wants to modify it for themselves or make it parametric and what not. Have at it. I left empty folders as placeholders if I ever get around to making the other sizes, so don't be weirded out that when the only parts you see start with E instead of A. 😂. There are two versions, the standard which uses the 12mm x 3mm magnets, and the heavy duty which uses 16mm x 5mm magnets.

• Part E5b_5x5 HeavyDooty Baseplate

• Part E0_Extras (magnet inserts you can move around and customize)
